i am trying to load the uclinux image for the de2 board. i've loaded the sof and pof and downloaded using the wiki instructions. i keep getting the following message..

downloading 630kb in 7.7s

verfying 00500000 <0%>

verify failed between address 0x500000 and 0x502a19

anybody know why i can&#39;t get this working? i&#39;m using the de2_net project and zimage_de2_net files. it should work but for me it doesn&#39;t. please help me make this de2 board more than a 500$ paper weight that blinks.

The sdram address range of de2 is 0-0x00800000.

The zImage will be loaded to 0x00500000.

SO it loaded, but verify failed.

Do you use quartus2 v6.0 sp1, nios2 v6.0 sp1, de2 system disc v1.3 ?

Do you use quaruts2 to config the de2 with DE2_NET.sof before nios2-download?

The config data of fpga will lose when power off.

Have you tried some demo programs from sdram?
